Hello Art,
We will not be upgrading to version 6.13 on these systems as they are not
robust enough to support the local logging inherent in the new version.
I will check in with my team on if there are any further actions we can
take to try and troubleshoot this issue, but I fear we may be at the limit
of our ability to make this better.
I’ll let you know tomorrow where we stand. Thanks.
Anne
